Make a box-and-whisker plot of the data.
21, 21, 22, 20, 13, 13, 27, 24
does anyone know the answers??
oh -- so you're trying to cheat, with no effort on your part.
We generally frown on that here.
I SHALL PUT THIS TO THE TEST!!!!!!!!!
1. B
2. D
3. C
4. D
The test is the 3.5.5 - Quick Check: Box-and-Whisker Plots
If anyone posts all the answers, both Keanu and that person will get themselves banned.
Be aware of what you're doing!
Thx, guys Benedict Cumberbatch is right.
To create a box-and-whisker plot for the given data set {21, 21, 22, 20, 13, 13, 27, 24}, you can follow these steps:
1. Order the data in ascending order: {13, 13, 20, 21, 21, 22, 24, 27}.
2. Find the median (middle value) of the data. In this case, there are 8 values, so the middle two values are 21 and 22. Therefore, the median is (21 + 22) / 2 = 21.5.
3. Determine the lower quartile (Q1). This is the median of the lower half of the data set. In this case, the lower half is {13, 13, 20, 21}. The median of this lower half is (13 + 20) / 2 = 16.5, which is the lower quartile (Q1).
4. Determine the upper quartile (Q3). This is the median of the upper half of the data set. In this case, the upper half is {21, 21, 22, 24}. The median of this upper half is (21 + 22) / 2 = 21.5, which is the upper quartile (Q3).
5. Find the minimum and maximum values in the data set. The minimum value is 13, and the maximum value is 27.
6. Draw a number line that covers the range of the data set from the minimum value to the maximum value (13 to 27).
7. Place a box on the number line with the lower edge at Q1 and the upper edge at Q3. Draw a line within the box to represent the median (Q2).
8. Add two lines from the box, one extending from the lower edge (Q1) to the minimum value (13), and another extending from the upper edge (Q3) to the maximum value (27). These lines are called whiskers.
Your final box-and-whisker plot for the given data set {21, 21, 22, 20, 13, 13, 27, 24} should show the box representing the interquartile range (Q1 to Q3), the median line (Q2), and the whiskers extending to the minimum and maximum values.
google will provide you with many examples.
I'm sure you can modify one of them to use your data.
